Carlos quiles' maps are not very well researched once you realize what sources he pulls from. Most disasterous example is his map on Khvalynsk being ancestral Suverovo-Novodanilovka and Repin, based on a single paper by dragunov from before the 2000s.
They are good looking maps and are quite impressive simply because of the sheer amount of things he manages to fit into them but the majority of the things presented all pulls from singular sources or his own twisted interpretations The boundaries are also not very accurate
Also he died in 2021 or something so this leaves a perfect hole for me to fill... I love filling holes yuppp
@VVeltkrieger I grew up on his maps but I always took some of the connections with a grain of salt. He did update the maps fairly often I think
@darkwanderer64 Indeed. They are good maps, but there are certainly alot of issues. (He himself also pushed some insane theories) i still look at them now and again when im jumping into a new period and region, but i later realise how much is wrong from doing my own research
